I have this problem where I can never decide on a wallpaper for my phone. It's a constant struggle bordering on OCD. It might be OCD...I should check on the specifics...
Right, anyway...if you're a member of the Android Master Race and have problems deciding on a wallpaper, then you should absolutely check out Muzei. It's a recently launched live wallpaper app that cycles images every 12-24 hours based on a theme that you decide. There are dozens of plug-ins that you can add to the app to give your images some personal flair, such as my current go-to, Comic Cover. While it doesn't entirely kill the OCD of finding the "perfect" background, there is something to be said about an app doing the heavy lifting. Also, as I did just start using the app and it is a live wallpaper, I'll report back in a few days with battery stats if one of the five people that read this article are worried about anyone battery life.
